Add support for include and includedir directives to krb5.conf
This adds support for include and includedir statements in krb5.conf, and a quick DEP8 test for this functionality.
The patches are straight cherry-picks from upstream, and have some offset which I didn't fix on purpose.
Closes: #1074775
UPDATE: marking as draft because the two extra patches I just added seem to be causing build-time test failure, investigating...
UPDATE2: OK, fixed, was missing a 4th patch. This builds in sid, and the DEP8 test passes there too.
